Topological phases

…of interest include quantum magnetism, topological phases, superconductivity and spintronics.

…strongly correlated electrons, topological phases, superconductivity, quantum spin liquids and open many-body systems. The group also connects ultracold-atom dynamics and quantum-information concepts with condensed-matter theory. Applicants must hold, or obtain before starting, a doctorate based on theoretical condensed-matter research; the postdoctoral classification generally covers the first five years after the doctorate. The position is at RIKEN’s Wako campus, with annual contracts renewable subj

…describe bosonic anyon condensation in topological phases. The framework classifies possible condensations and identifies the degrees of freedom of the resulting models. Its microscopic categorical description refines the usual modular-tensor-category perspective and gives algorithms for calculating the categorical quantities through physical model data.

…and interpretable estimates of topological phases. The method also supplies an efficient initialisation for tensor-train optimisation and improves the memory–computation trade-off in model compression.
